Mirror-like effect inks resin for PET
mirror inks currently used is very wide, such as the IMD technology
used in the mobile phone keypad, washing machine, microwave oven
control panel function indicator panel and signs, washing
machine,electronic products on the decorative part; and the use of
specular color ink the decoration is more on a higher level than
the ordinary inks, make the product with landscaping.

Function:
Great sdhesion to cross-cut test and resistance to scraping by
fingernail.
Some problems when use:
1, Bad adhesion of Mirror-effect ink after printing:
Reason:general speaking, in order to guarantee the good mirror effect of
printing ink, the content of resin is relatively low, so that
affect theadhesion of ink, which is determined by ink's
characteristics.
Solution:by increasing volume of resin and using hardener agent.
2, Bad mirror effect of ink after printing:
Reason:a,Not suitable printing substrate is selected, mirror-effect ink
show the great mirror effect when it was printed in the high
transparentmaterials such as PET/PC/Glass, but not good mirror
effect in the ordinary materials
b,In order to increase the adhesion of mirror-effect ink, some
customers add transparent oil or other additives into it, that
affect themirror effect of ink.
c,When the printing substrate of no resistance to solvent is used,
strong solvent will corrode the substrate and affect the mirror
effect.
3, Problem of screen blockedby mirror-effect printing ink:
Reason:In order to have good mirror effect, the resin content of
mirror-effect ink is relatively low, at the same time, in order to
get the normalviscosity of ink, the content of solvent in the ink
is relatively high, however, the volatile speed of solvent is so
fast and it makes theproblem of blocking screen by printing ink. So
the mirror-effect printing ink should be printed at fast speed.
